Hey there, sorry about this - Dreamstone was actually not a feature meant to be released yet but I think it was accidentally leaked in v0.24 - can you send your savefile to havendockyyz@gmail.com? I will fix it for you as I did with boneyard96 via email and also refilled his Skill Points.
Enter this into file explorer to view savefiles: %USERPROFILE%\AppData\LocalLow\YYZStudio\Siegeturtle\
File0.st is your latest manual save - whereas the autosaves (you can check the date modified) are the game's most recent auto saves.
For belts, LUK adds crit damage, whereas some belts have an additional line that adds crit rate - they're both different things - by right crit rate is a little more rare to obtain, so it is a tradeoff if wearing a belt that adds more crit rate than cri damage (usually better).
For dolphin blessing - are you sure that the buff has been activated on your character? It should appear as an icon with a duration going down below the character's HP and MP bar. Still, I will check this out to confirm that it is adding correctly.
Progress automatically continues when you update the game to future versions - and even from the demo into the full version when it comes out later.
Thanks so much for all the feedback, I will check them out and address all issues in the coming updates! Really appreciate the sharing.
